a Map showing sampling locations and overall genetic structure. b Population structure of 94 individuals based on ADMIXTURE analysis at K = 2 and 3. c Demographic history of the three lineages of B. insignis, with the three glacial events (MIS2, LGM, and MIS6) highlighted in light blue. d Schematic of the best demographic scenario inferred with fastsimcoal2. Numbers at the bottom indicate the estimated Ne of each lineage; and the bidirectional arrow shows the direction of gene flow. e Heatmap illustrating haplotype sharing among individuals, where colors represent the total length of identity-by-descent (IBD) blocks for each pairwise comparison.
